1954 Map of Tioga

USGS Topo · Published 1986

About this map

The Tioga River and Cowanesque River valleys define the landscape of this northern Pennsylvania region during a period of significant hydrological change. Revisions from the 1980s illustrate the impact of flood control projects, showing the expansion of Cowanesque Lake and the Tioga Dam, which created the Tioga Reservoir and the Crooked Hammond Reservoir. These major water bodies transformed the valley floor near settlements like Tioga, Nelson, and Tompkins.
